Roslyn is an engineer. She is designing a part for a new engine. The length of the part is 16 centimeters (cm), the width is 6 cm, and the height of the cone top is 5 cm, as shown.
Answers
[tex]\bold{\huge{\underline{ Solution }}}[/tex]
Given :-The length of the part is 16 centimeters The part of new engine is composed of 1 cone, 1 cylinder and 1 hemisphere The width of the engine is 6 cmThe height of the cone is 5 cmTo Find :-We have to find the total volume of the part Let's Begin :-Let divide the part of engine into three parts as it is composed of 3 different figures.
We know that,
Volume of cone
[tex]\bold{=}{\bold{\dfrac{ 1}{3}}}{\bold{{\pi}r^{2}h}}[/tex]
Here, we have,
The height of the cone is 5 cmThe diameter of the cone is 6 cmTherefore, Radius of the cone = 3 cmSubsitute the required values,
Volume of the first part that is cone
[tex]\sf{=}{\sf{\dfrac{ 1}{3}}}{\sf{ {\times}3.14{\times}(3)^{2}{\times}5}}[/tex]
[tex]\sf{=}{\sf{\dfrac{ 1}{3}}}{\sf{ {\times}3.14{\times}9{\times}5}}[/tex]
[tex]\sf{ = 3.14 {\times} 3 {\times} 5 }[/tex]
[tex]\sf{ = 3.14 {\times} 15 }[/tex]
[tex]\sf{ = 3.14 {\times} 15 }[/tex]
[tex]\bold{ = 47.1 cm^{3} }[/tex]
Thus, The volume of cone is 47.1 cm³ .
For second part Second part is composed of cylinderWe know that,
The volume of cylinder
[tex]\bold{ = {\pi}r^{2}h }[/tex]
Here,
The diameter of the cylinder is 6 cmSo, Radius = 3 cmThe length of the cylinder = 16 - (Length of cone + Length of hemisphere) Length = 16 - 11 = 5 cmSubsitute the required values in the above formula,
Volume of the second part that is cylinder
[tex]\sf{ = 3.14{\times} (3)^{2}{\times} 5}[/tex]
[tex]\sf{ = 3.14{\times} 9 {\times} 5}[/tex]
[tex]\sf{ = 3.14{\times} 45 }[/tex]
[tex]\bold{ = 141.3 cm^{3}}[/tex]
Thus, The volume of the cylinder is 141.3 cm³
For third partThird part is composed of hemisphereWe know that,
Volume of hemisphere
[tex]\bold{=}{\bold{\dfrac{ 2}{3}}}{\sf{ {\pi}r}}[/tex]
Here,
The diameter of the hemisphere is 6 cmSo, Radius = 3cmSubsitute the required values,
Volume of third part that is hemisphere
[tex]\sf{=}{\sf{\dfrac{ 2}{3}}}{\sf{{\times} 3.14 {\times}3}}[/tex]
[tex]\sf{ = 2 {\times} 3.14 }[/tex]
[tex]\bold{ = 6.28 cm^{3} }[/tex]
Thus, The volume of the hemisphere is 6.28 cm³
Therefore,The total volume of the part
= Volume of cone + Volume of cylinder + Volume of hemisphere
[tex]\sf{ = 47.1 + 141.3 + 6.28 }[/tex]
[tex]\sf{ = 188.4 + 6.28 }[/tex]
[tex]\sf{ = 194.68 cm^{3} }[/tex]
[tex]\bold{ = 194.7 cm^{3} }[/tex]
Hence, The total volume of the part is 194.7 cm³ .

Age of car = 6 years.
Original cost = $12,995.
The current market value is $
Answers
The original value of the car of $12,995, and 10% value and 6% repair
cost, give the actual current market value of the car as; $1,234.525.
How can the current value of the car be calculated?The market value of the car is found as follows;
The age of the car = 6 years
Original market value of the car = $12,995
The percentage of the market value after 6 years = 10%
The percentage of the value used for repairs ≈ 5%
Current market value = Book value - Cost of repair
Book value = $12,995 × 0.1 = $1,299.5
Cost of repair = $12,995 × 0.1 × 0.05 = $64.975
Current market, value = $1,299.5 - $64.975 = $1,234.525

Answers
Step-by-step explanation:
As per given Information
Slope m = 4
That line goes through the point (2,-3)
Using Point Slope Form
y - y₁ = m ( x - x₁)where,
y₁ = -3
x₁ = 2
from the given information
On putting the value we obtain
↝ y-(-3) = 4 ( x - 2)
↝ y + 3 = 4x - 8
↝ y = 4x -8 - 3
↝ y = 4x - 11
So, the point slope equation for that line is y = 4x-11 .

5x+2y=1
Y=-x+2
Answers
Answer:
X = -1
Step-by-step explanation:
Rewrite equations:
y = -x + 2; 5x + 2y = 1
Step: Solve y = -x + 2y = 1 for y:
y = -x + 2
Step: Substitute -x + 2 for y in 5x +2y =1 :
5x +2y = 1
5x +2 (-x+2) =1
3x + 4 =1 (simplifiy both sides of the equation)
3x + 4 + - 4 = 1 + -4
(Add -4 to both sides)
3x = -3
3x/3 = -3/3 (Divide both sides by 3)
x = -1

Here is a set of signed numbers: 7, -3, 1/2, -.8, .8, 1/10, -2
1) If their numbers represent temperatures in degrees Celsius, which is the coldest?
Answers
Answer:
-3 would probably be the coldest
Step-by-step explanation:
based on my research the higher the number in celsius the hotter it is. the lower the number the colder it is. and since -8 is the lowest it is the coldest temperature.
also may i ask what you dont understand? i can help you
edit
so the choices are
7 , -3 , 1/2 , -0.8 , 0.8 , 1/10 , - 2
we can ignore the choices without the negative signs so..
-3, -0.8, and - 2
is what we have left
-0.8 would not be the coldest because it is not the lowest value
-2 would not be the coldest because it is not the lowest value
-3 is the coldest because it is the lowest value.
You may think that -3 should be the highest since it has "3", but in negative its different. -1 would be greater than -5 because it is closer to 0

A population of a town is divided into three age classes: less than or equal to 20 years old, between 20 and 40 years old, and greater than 40 years old. After each period of 20 years, there are 80 % people of the first age class still alive, 73 % people of the second age class still alive and 54 % people of the third age Hare still alive. The average birth rate of people in the first age class during this period is 1.45 (i.e., each person in the first age class, on average, give birth to about 1.45 babies during this period); the birth rate for the second age class is 1.46, and for the third age class is 0.59, respectively. Suppose that the town, at the present, has 10932, 11087, 14878 people in the three age classes, respectively.
